The Andean genera Lurama Schaus, 1928 and Ulmara Schaus, 1928 are revised. Lurama poses difficulty for revision due to lost male genitalia of the types of both described species. Ulmara conjuncta sp. n., U. azurula sp. n., and U. dombroskiei sp. n. are described as new in the genus Ulmara. A lectotype is designated for Lurama quindiuna Schaus, 1928 and Ulmara rotunda (Dognin, 1916). A new monotypic genus, Cunicumara gen. n., which is externally similar to Ulmara, is described to include the new species Cunicumara anae sp. n. from low elevations of Bolivia and Paraguay. Male genital morphology does not support a close association of Cunicumara with Lurama or Ulmara. The latter two genera, however, are closely related based on similarities of male genitalia and biogeography.

Several recent works have been published focusing on the taxonomy of the previously understudied Mimallonidae, wherein 47 new species and four new genera have been described since 2012 (
The present article revises two small and closely related genera, Lurama Schaus, 1928 and Ulmara Schaus, 1928, which are both endemic to high elevations (up to 3500 m) of the Andes, and describes an externally similar new, monotypic, genus from Bolivia and Paraguay. The genus Lurama currently consists of two species: L. penia (Dognin, 1919) and L. quindiuna Schaus, 1928. The monotypic genus Ulmara contains U. rotunda (Dognin, 1916). Both genera are diagnosed based on external characters and male genitalia, and all currently known species are redescribed. The female of L. quindiuna is described and figured for the first time, and three new species are described in Ulmara.

Lurama is immediately recognizable in both sexes among Mimallonidae by the yellow, yellow-gray, light-brown, or tan coloration of all wings, combined with prominent brown ante- and postmedial lines that strongly contrast against the lighter ground color. Wing veins are usually obvious and contrast against the ground color due to prominent brown scales lining them. Male genitalia are simple, but recognizable by the broad, short valves and the setae-covered lobes projecting from the transtilla. In Lurama the phallus is very narrow, pointed, and curved, being somewhat fishhook shaped. Lurama male genitalia are most similar to those of Ulmara, but can be distinguished by the following characters seen in Lurama: a much narrower phallus, less triangular valves, the absence of the gnathos, setae-covered structures on the ventrum of VIII, and teeth on the valves. The female genitalia are small, but stout and robust structures, with extremely reduced apophyses anteriores and corpus bursae. The highly reduced corpus bursae is the smallest in overall size in the family (compared to those examined so far). The female genitalia are similar in general structure to those of the female of Ulmara, but the genitalia of Lurama lack the broader, setae-covered lateral posterior lobe of VIII, and have a larger, though still very small by mimallonid standards, ductus bursae and corpus bursae, reflecting the much broader phallus of Ulmara relative to the extremely thin phallus of Lurama.
Male.Head: Tan brown to straw colored, eyes very large, occupying more than two thirds area of head, bordered posteriorly by dark scales; antenna coloration as for head, bipectinate to tip; labial palpus very reduced, three segmented, tufted ventrally, especially basal-most segment, palpus not extending beyond frons, heavily clothed in long scales, scales darker dorsally. Thorax: Coloration as for head, though it may be somewhat lighter, lustrous gold overall, darker-brown scales present on prothoracic collar. Legs: Coloration as for thorax, vestiture fine, appearing as spun gold. Tibial spurs somewhat elongated, tubular, clothed in scales except for tip. Forewing dorsum: Forewing length: 14.5–18 mm, wingspan: 27–35 mm, n=24. Variable overall; short, subtriangular to triangular, margin nearly straight from apex until after passing M3 where wing smoothly curves toward anal margin. Ground color variable from brown to tan to nearly yellow, overall lightly to heavily speckled by dark-brown or brown-gray petiolate scales, especially postmedially. Antemedial line brown, narrow to relatively wide, occasionally somewhat diffuse, slightly bowed outward. Postmedial line nearly straight or slightly curved inward from anal margin to Rs3, Rs4, or between Rs3 and Rs4, where line abruptly angled toward costa, forming nearly right angle, coloration and width as for antemedial line. Antemedial, medial, and postmedial areas concolorous, distance between lines variable. Costa and outer wing margin darker brown as in ante- and postmedial lines. Discal spot a dark-brown streak spanning width of discal cell, mesally slightly angled inward toward cell. Wing veins lined by dark-brown scales, colored as ante- and postmedial lines. Fringe poorly preserved (L. penia) or light brown with intermittent darker-brown scales. Forewing ventrum: Similar to dorsum but usually lighter; antemedial line nearly absent to absent and postmedial line may be lighter. Hindwing dorsum: Coloration as for forewing dorsum, antemedial line absent, postmedial line straight or curved outward. Hindwing ventrum: Following same pattern as forewing ventrum but postmedial line always curved outward. Base of wing usually covered by dark-brown scales from thorax. Frenulum present as single bristle, size somewhat variable. Venation: CuA1 arising nearly midway between lower angle of cell and CuA2; M2 and M3 arise from essentially same point of lower angle of cell, otherwise typical of Mimallonidae. Abdomen: Concolorous with thorax, distal tip with tuft of black scales. Genitalia: (Figs
Lurama is a small, easily recognizable genus endemic to relatively high elevations of the Andes of Colombia and Ecuador. See individual species remarks for unresolvable issues pertaining to the type specimens of the two named species. A holistic revision is not possible for Lurama due to the issues pertaining to the type material of the named species; however, the genus is included in the present work due to the biogeographic similarity to Ulmara and the obvious homology in structures of the male and female genitalia. I recognize that more than one taxa likely exists under the name L. quindiuna in the present treatment, however due to aforementioned issues which will be explained in detail in each respective species remarks sections, no new taxa are described in Lurama.

Lurama penia can be distinguished from L. quindiuna by the smaller size, shorter, more rounded wings, and somewhat more diffuse, broader postmedial and antemedial lines on the wings. The lines are also closer together and farther from the wing margin than in L. quindiuna. Additionally, the forewing postmedial line has its apical angle intersecting Rs4 very near the fork of Rs3+Rs4, rather than being much more distant from this fork in the other species.
Male.Head: As for genus but tan brown. Thorax: Coloration as for head, darker-brown scales present on prothorax. Legs: Coloration as for thorax, poorly preserved. Forewing dorsum: Forewing length: 14.5 mm, wingspan: ~27 mm, n = 1. Short, vaguely triangular, margin nearly straight from apex until after passing M3 where wing smoothly curves toward anal margin. Ground color yellowish tan, overall lightly speckled by dark petiolate scales, especially postmedially. Antemedial line brown, relatively wide, somewhat diffuse, slightly curving outward. Postmedial line nearly straight from anal margin to Rs4 where it abruptly angles toward costa perpendicularly, coloration and width as for antemedial line. Antemedial, medial, and postmedial areas concolorous. Costa and outer wing margin darker brown. Discal spot a dark streak spanning width of discal cell, mesally slightly angled inward toward cell. Forewing ventrum: Similar to dorsum but with more concentrated speckling postmedially; antemedial line nearly absent, postmedial line fainter. Hindwing dorsum: Coloration as for forewing dorsum, antemedial line absent, postmedial line not reaching anterior wing margin. Hindwing ventrum: Following same pattern as forewing ventrum but postmedial line curved outward rather than straight as on dorsum. Abdomen: Partially missing, but anterior segments concolorous with thorax. Genitalia: Not examined. Female. Unknown.
This species is apparently very rarely collected, as it is known only from the male holotype. Unfortunately, the genitalia preparation of the holotype, probably made by Carl Heinrich (R. Hutchings pers. comm.), is lost and could not be located by the individuals tasked with trying to find it at the
As for L. quindiuna below, the issue of missing type genitalia for these two species results in some difficulties determining the identity of non-type specimens. Fortunately, external diagnostic characteristics are ample enough to maintain both currently described species as valid, but prevents me from describing new species in the genus at this time. It is vital that more material be located for this and the following species at each of their respective type localities so that more conclusive diagnostic characters can be given, particularly in regards to the genitalia.

Lurama quindiuna can be distinguished from the previous species by the larger size, more triangular wings, and by the (usually) thinner, more well-defined ante- and postmedial lines. The lines are situated closer to the wing margin than in L. penia, and form a sharp angle apically. Additionally, the forewing postmedial line has its apical angle either intersecting Rs4 or between Rs3 and Rs4 and is distant from the fork of Rs3+Rs4.

Confusion surrounds the whereabouts of the genitalia of the lectotype of L. quindiuna. When initially examining the lectotype, I noticed that the abdomen was visibly small and noticeably lighter in color relative to the rest of the specimen. The abdomen was odd enough that it appeared out of place on the specimen, and a dissection further supported this notion. The dissection revealed complicated genitalia unlike any other in Mimallonidae, especially compared with other dissections of L. quindiuna from nearby locations. The elongated saccus and thin, golf club like phallus is reminiscent of some Bombycidae (pers. obs.), whereas the valve structure is similar to some Notodontidae. Alexander Schintlmeister (pers. comm.) has suggested Lasiocampidae rather than Notodontidae and Daniel Herbin (pers. comm.) mentioned the possibility of it belonging to Phiditiidae although Joël Minet (pers. comm.) does not consider this likely due to the presence of a saccus. So far, the exact determination of the genitalia is inconclusive. Apparently the abdomen of the L. quindiuna lectotype was misplaced and incorrectly replaced with a foreign abdomen at some point after its original description. Wolfram Mey (pers. comm.) confirmed that this, unfortunately, is a known issue with material in the MNHU. Furthermore, it is worth noting that
By Article 73.1.5, the abdomen (and my subsequent genitalia preparation: St Laurent diss.: 2-14-16:1) is hereby excluded from the lectotype of Lurama quindiuna, and although it will be preserved for historical purposes, it cannot be considered a component of this lectotype (
The lectotype of L. quindiuna differs in maculation from the series from Bogotá, particularly in regards to the arrangement of the forewing postmedial line. In the lectotype, the postmedial line is farther from the wing margin, angled toward the costa more proximal to the fork of Rs3 + Rs4, and has an apical angle that intersects Rs4 rather than being situated between Rs3 and Rs4. Furthermore, the postmedial and antemedial lines are closer together in the lectotype. While these characters were nearly consistently different between the lectotype and all specimens from Bogotá, Pueblo Guasca, substantial variations in these same characters were found within the Pueblo Guasca series (compare Figs
Female genitalia, however, do differ between Colombian and Ecuadorian L. quindiuna specimens. The width of the VIII tergite, shape of papillae anales and lamella antevaginalis, as well as the size of the corpus bursae all differed between these locations. However, given the lack of differentiating characters in the usually much more reliable male genitalia (pers. obs.) as well as the low sample size of female specimens, it does not seem reasonable to consider the Colombian and Ecuadorian populations separate species based on this information alone. Molecular evidence may later be useful in comparing these two populations, although recently collected Colombian material is currently lacking.
It is critical to locate more material of L. quindiuna from the type locality at Paso del Quindío, Colombia, so that the necessary genitalia comparisons between topotypical and other populations can be made. Also, it would be important to determine if populations from Paso del Quindío display similar levels of variation as in the other examined populations to further justify conclusions presented in the present work.

The unique genus Ulmara shows no apparent external resemblance to any known Mimallonidae. The stout, broad wings, dark, nearly black coloration, serrated postmedial lines, combined with impressively long pectinations of the antennae in males, are all characters that should immediately allow the recognition of Ulmara. Although the long pectinations of the antennae are seen in the other two genera treated in the present work, neither genus is so darkly colored. Cunicumara gen. n., described below, is similar in having both broad antennae and stout wings, but is easily distinguished by the straight, rather than serrate postmedial line present in Ulmara. The male genitalia of Ulmara are actually rather similar to those of Lurama (see diagnosis of Lurama) but wholly unlike those of Cunicumara gen. n. The genitalia of Ulmara are recognized by the short, broad phallus with a scoop-like ventral projection, apically-toothed valves, and the unique, paired, setae-covered sclerotizations on the ventrum of VIII, which are variously connected to an extension of the saccus.
Male.Head: Very dark brown to nearly black, eyes very large, occupying more than two-thirds area of head; antennal coloration pale tan to dark brown, if lighter in color, contrasting against dark head, scape with contrasting pale off-white tuft of scales, antenna bipectinate to tip, pectinations very long, the longest nearly one-fourth length of antenna overall; labial palpus relatively long, extending beyond head, three segmented, tufted ventrally, heavily clothed in long scales. Thorax: Coloration as for head but often with pale-gray to brown scales beneath darker-black to steel-blue scales, vestiture very long, shaggy, scales thin, scales of prothorax lighter brown. Legs: Coloration as for thorax, but lighter ventrally, vestiture fine, elongated. Femur and tibia clothed in particularly long scales. Tibial spurs somewhat elongated, tubular, clothed in light khaki-colored scales except for naked tip. Forewing dorsum: Forewing length: 17.5–21 mm, wingspan: 34–43 mm, n=16. Short subtriangular, margin convex, apex barely accentuated. Ground color usually very dark grayish black, often with nearly steel-blue sheen, older and worn specimens expose lighter pale-brown scales beneath thicker, darker-scales; wider petiolate scales absent. Antemedial line brown, zigzagged, usually obscured by darker surrounding scales so line nearly absent. Brown postmedial line serrated at each wing vein, postmedial line may be very distinct, especially when lighter scales present along inner side, and near tornus, or postmedial line may be overshadowed by darker surrounding scales; line angled toward costa at Rs4. Between Rs4 and costa, line slightly undulated, but otherwise less serrate, may be notched near costa. Location of postmedial line variable, from one-fourth wing length distant from wing margin to nearly two-thirds distant. Antemedial, medial, and postmedial areas concolorous, although postmedial area may be lighter gray blue than medial area, particularly along postmedial line. Discal spot a small white mark, either somewhat circular in shape or oblong. Fringe consisting of elongated scales, coloration as for medial area except some lighter off-white scales present in semi-regular pattern along margin. Forewing ventrum: Similar to dorsum but much lighter, grayer, maculation reduced; antemedial line absent, postmedial line less distinct to nearly absent, brown outline lacking if present on dorsum. Hindwing dorsum: Coloration as for forewing dorsum, antemedial line absent, discal mark absent, outer margin of wing may be serrate or mostly smooth. Hindwing ventrum: Following same pattern as forewing ventrum. Base of wing sometimes covered by dark-brown scales emanating outward from thorax. Frenulum present as single bristle. Venation: Similar to Lurama but CuA1 arises nearer to lower angle of cell; M2 and M3 do not originate from same point at lower angle of cell, and are more separated. Abdomen: Concolorous with thorax, but usually slightly lighter brown, distal tip with paired tuft of elongate scales. Genitalia: Simple; vinculum somewhat box-like or ovoid, ventrally with reduced saccus, projection of saccus attached to VIII, forming paired, setae-covered sclerotizations. Uncus simple, highly truncated apically with triangular base or broad basally, with reduced apical extension, laterally uncus beak-like. Gnathos variable, from nearly absent, to mesally gapped, to a single fused plate. Valves short, generally triangular, somewhat truncated apically, with single tooth projecting from saccular edge near apex of valve, tooth variable in length. Transtilla with weakly sclerotized, inward-facing setae-covered extensions, setae variable in thickness from very fine to thick. Setae pointed outward directly over phallus. Diaphragm forms small, balloon-like sac expanded inward into abdomen, sac covered in fine, inward-facing setae surrounding phallus. Juxta partially fused to phallus, encircling it, lightly sclerotized, especially dorsal to phallus. Phallus short, stout, anterior half tubular or bent, apex more heavily sclerotized, forming scoop-like extension below vesica; vesica small, sac-like, weakly scobinate, poorly differentiated diverticula may be present; base of phallus much narrower than apical half, but variable in thickness, angled backward from apex of phallus. Female.Head: As for male, but antennae much smaller overall, pectinations particularly shorter, labial palpus slightly reduced. Thorax: As for male. Legs: As for male, but vestiture seemingly sparser. Forewing dorsum: Forewing length: 21.5 mm, wingspan: 41 mm, n=2. As for male but more elongated, slightly narrower, discal mark reduced. Forewing ventrum: Similar to dorsum but much lighter, grayer, maculation reduced; antemedial line absent, postmedial line less distinct. Hindwing dorsum: Coloration as for forewing dorsum, antemedial line absent. Hindwing ventrum: Following same pattern as forewing ventrum. Frenulum as multiple bristles, length shorter than in male. Abdomen: Concolorous with thorax, similar to male but not truncated to a point. Genitalia: (Fig.
The genus Ulmara contains some of the darkest colored and highest elevation inhabiting Mimallonidae, and is immediately recognizable by characters given in the diagnosis. Most species in the genus are quite similar to one another, but can be primarily differentiated by male genitalia. Distribution and overall size should also be adequate for simple diagnosis.

Ulmara rotunda is the largest and most northernmost representative of the genus, being the only species so far reported from Colombia. Apart from distribution and large size, U. rotunda can be recognized by the nearly complete gnathos, which while not fused mesally, is only separated by a small gap with heavily sclerotized terminal ends on either side of the gap. The valves are among the largest in the genus, and are triangular, the phallus is also recognizable by its oblong shape where the distal half is much wider (when viewed laterally) than the basal half.

This new species is most similar to U. rotunda in external appearance, but can be distinguished from it by the more southerly distribution, darker, nearly black ground color, smaller size overall, lack of a brown inner edging along the postmedial line of the fore and hindwings, and the near absence of the postmedial line on the ventrum of the wings. The male genitalia also offer good characters for differentiation: in U. conjuncta the gnathos is fused mesally, giving rise to a thin plate-like extension, smaller, more rounded valves, and the sharply downwardly bent phallus, which is much thinner overall and more elongated at the ventral apex. Other characters, such as the setae-covered sclerotizations on the ventrum of VIII, also differ, but are less readily useful in recognizing U. conjuncta.

This species is named for the complete, connected (conjuncta Latin), gnathos, a character unique to this species in the genus.
Ulmara conjuncta, although similar to U. rotunda, is easily distinguished by both distribution and all characters given in the diagnosis. According to the data on the labels of a number of specimens collected by Jan Hillman, this species can be collected in “virgin humid forests” as well as “disturbed” forests, pastures, and “deforested haciendas.”
This is the only species in the genus with a well-defined gnathos, which, when present, is an important character for distinguishing similar species within genera in Mimallonidae (pers. obs).

Ulmara azurula is the smallest species in the genus (on average), and so far the only species known from central Peru. The small size and distribution should allow this species to be distinguished from the previous two. The following characters differentiate U. azurula from the most similar species, U. dombroskiei sp. n. to be described below, but also differentiate it from both U. rotunda and U. conjuncta. Although U. azurula is externally similar in size and coloration to U. dombroskiei sp. n., namely by the metallic bluish sheen, in U. azurula, the postmedial line of the fore and hindwings is located closer to the wing margin than in U. dombroskiei sp. n. Furthermore, the width of the splayed, setae-covered sclerotizations of VIII are much wider than the vinculum, whereas in U. dombroskiei sp. n. these sclerotizations are highly reduced overall, and have shorter setae. Additionally, the gnathos of U. azurula is the most reduced of the entire genus, and exists as only weakly-sclerotized lateral bars, whereas in U. dombroskiei sp. n. the gnathos nearly converges mesally. The setae-covered flaps projecting inward from the transtilla in U. azurula bear thicker setae than in any other Ulmara. Finally, the phallus shape is perhaps the best genital character for distinguishing these two Peruvian species: in U. azurula the phallus is uniformly cylindrical from a dorsal perspective, whereas in U. dombroskiei sp. n. the phallus is very wide distally.

This species is named for its small size (diminutive –ula Latin) and blue (azurea Latin) iridescence.
Although the known range of this species is located between the distributions of U. conjuncta in Ecuador and U. dombroskiei sp. n. in southern Peru, U. azurula is not intermediate in external or genital morphology between these species, but is instead more similar to U. dombroskiei sp. n. than either previously described species. Considering the consistently smaller size, almost entirely absent gnathos, narrower phallus, and more elongated saccular extensions relative to U. dombroskiei sp. n., as well as previously mentioned wing characters, this species is apparently distinct from the southern Peruvian populations named U. dombroskiei sp. n. below. The iridescent blue sheen, characteristic of the genus Ulmara, is most distinct in the Peruvian species, but is not clearly reproduced in photographs.

This species is most similar to U. azurula, see the diagnosis of that species for characters necessary for differentiation. However, it is worth repeating the characters entirely unique to this species in the entire genus: postmedial line somewhat variable in distance from wing margin but may be as far as one-third wing length away from the margin, the gnathos is reduced but nearly converges mesally (or does so very weakly), and is overall not heavily sclerotized, distinguishing it U. rotunda, the uncus is highly truncated, the saccular extensions are highly reduced, and the phallus is very wide distally.

This species is named for Jason Dombroskie (
As previously mentioned in the remarks for U. azurula, the two Peruvian species, although distinct, are related, given the reduction of the gnathos, the small valves, and the blue iridescence of the wing scales. As mentioned previously, this blue iridescence is not well represented in the figures.
Although five specimens and three dissections of U. dombroskiei were examined when writing the description, only one specimen (the holotype) is from Agualani at the higher elevation. This specimen displayed the most accentuated characters that define this species, namely the very broad phallus and the postmedial lines of the fore and hindwings, which are relatively distant from the wing margin. Therefore, this specimen is designated as the holotype. The differences between the holotype and paratypes, namely slightly less broadened phallus and postmedial line located nearer to the wing margin, may be due to elevation differences considering the proximity of the localities and the otherwise same general structures of the genitalia.
Cunicumara anae St Laurent, 2016, sp. n.
The name for this new genus comes from cuniculus (Latin), meaning rabbit, referring to the somewhat layered appearance of brown coloration of C. anae sp. n., which is reminiscent of rabbit fur. Furthermore, the particularly long antennae relative to the size of the body and wings is quite remarkable, therefore the name is appropriate in calling to mind the long ears of a rabbit. The ending –mara notes a slightly superficial similarity to Ulmara.
This new genus can be recognized by the salmon to orange-brown, fading to light, sandy tan ground color, interspersed with gray, pale-khaki, and dark-brown scales, which give moths of this genus a somewhat hoary appearance. The wings are very broad, with a weakly accentuated, barely falcate apex. The long bipectinate antennae are more than half the length of the short forewings, and have distinctly long pectinations. The combination of these characters should immediately allow Cunicumara to be distinguished from all other known Mimallonidae. The complex male genitalia are also unique, characterized by the presence of a basally-fused, bifurcated gnathos, basally-toothed sacculus, and the phallus with curled, horn-like juxtal processes, which are dorsal to the phallus; a third, singular horn-like process arises between the curled juxtal processes .
Male.Head: Khaki brown, eyes very large, occupying more than two-thirds area of head, bordered posteriorly by dark scales; antenna coloration pale tan, very long, more than half length of forewing, antenna bipectinate to tip, pectinations very long, longest nearly one-fourth length of antennae overall; labial palpus very reduced, not extending beyond head, apparently three segmented, but segmentation obscured by thick tufts ventrally. Thorax: Coloration as for head but with gray-tipped scales giving thorax a hoary appearance overall. Legs: Coloration as for thorax, vestiture thick, long. Tibial spurs robust, covered in scales except for tip. Forewing dorsum: Forewing length: 14–15.5 mm, avg.: 14.8 mm, wingspan: 30–31 mm, n=3. Short, subtriangular, margin convex except for where concave very near apex; apex slightly falcate. Ground color light with slight salmon hue, especially along anterior half of wing until costa; wing with layered appearance due to presence of light-gray, dark-brown, and brown scattered scales, particularly contrasting gray scales concentrated basally and along costa, giving wing hoary appearance. Antemedial line very faint, light brown, somewhat wavy. Gray-brown postmedial line straight from anal margin until Rs4 where line angled toward costa. Antemedial, medial, and postmedial areas mostly concolorous, although ante- and medial areas appear lighter due to gray scales; likewise salmon and light-brown coloration of ground color most evident near apical angle of postmedial line and postmedially. Discal mark nearly absent, or as thick, dark streak spanning cell. Fringe poorly preserved in examined specimens, but consisting of elongated scales, coloration as for medial area except some lighter off-white scales present in semi-regular pattern along margin. Forewing ventrum: Very similar to dorsum but appearing lighter, due to more diffuse presence of gray scaling, dark-brown scales may also be more prevalent in some individuals; antemedial line absent, postmedial line less distinct, outwardly curved, roughly following wing margin in shape, not straight as on dorsum. Hindwing dorsum: Coloration, patterning as for forewing dorsum, but antemedial line absent, discal mark absent, postmedial line slightly curved following outline of wing margin, postmedial line may be very faint. Hindwing ventrum: Following same pattern as forewing ventrum, but lighter due to pale-khaki scales basally. Frenulum present as single bristle. Venation: More typical of Mimallonidae than either Lurama or Ulmara with respect to M1–M3, with each vein being more evenly spaced along obliquely angled cell, CuA1 arises from lower angle of cell; Rs3 + Rs4 short stalked. Abdomen: Lighter than thorax, with coppery luster in fresh specimen, fading to pale khaki in older material. Vestiture thick, long, distal tip of abdomen with elongated, dark-brown tipped scales. Genitalia: (Fig.
Cunicumara is distinct among the family Mimallonidae, externally bearing some resemblance to Ulmara by the presence of the massive antennae and the short, broad wings, while at the same time displaying male genitalia that in some ways resemble the distinct genus Menevia Schaus, 1928, namely the presence of complex juxtal processes and the basally bifurcated lobes of the phallus.

This species is named for Ana Paula dos Santos de Carvalho, a lepidopterist interested in the sexual dynamics of Papilionoidea. Ana is the best friend and source of the most joy in the author’s life.
This new species, and thus the genus Cunicumara in general, is very poorly represented in collections. However, very little Mimallonidae material is available from the type locality or similar regions in Brazil, Paraguay, and Bolivia, and thus the rarity of this species in collections is probably only due to under collecting. The two localities both border on the Brazilian Pantanal Biome (
